The study being undertaken was to ascertain the effect or effects of different firing conditions and colorants on glazes composed of wood ash from two trees indigenous to Texas. The problem was divided into two parts: first, to identify the best mixtures using the selected vegetable ash; second, to alter successful glazes with set percentages of colorants. The main objective of the study was to evaluate findings resulting from the variation of elements, firing conditions, and colorants used and to select successful glazes.
